Definitions

  • the invention relates to a method for the prevention of motion sickness, and an apparatus for detecting and signaling potentially sickening motions suitable for application in a method according to the invention.
  • Motion sickness can arise when a person is exposed to one or more specific motions for a longer period of time.
  • factors such as temperature, smell, mood and digestion can play a catalyzing role.
  • the best-known forms of motion sickness are sea sickness and car sickness. Especially the latter variant occurs frequently, in particular in children.
  • Many solutions have already been proposed to control motion sickness in general, and car sickness in particular.
  • preventatives on the market, which need to be ingested some time before a drive and then help to suppress the motion sickness and the accompanying clinical picture, such as nausea.
  • These known preventatives are generally not without side effects and so they are not suitable for every one or in every situation. This is also why the preventatives are less suitable for frequent, for example daily use.
  • it is inherent to their preventative nature that, in part of the cases, these preventatives will be taken unnecessarily, since they need to be ingested at a moment when it is not certain at all yet whether one will be motion sick during the drive involved.
  • car sickness preventatives are known, whose action is based on deception of the senses, particularly sight and hearing.
  • Specific auditory or visual signals are blocked or replaced with artificial, non-sickening sensory signals.
  • these solutions require complicated, expensive equipment and thus seem little suitable for practical daily use, for example in a bus or passenger car.
  • the object of this invention is a method for the prevention of motion sickness in occupants of a vehicle, wherein the abovementioned disadvantages of the known methods mentioned above have been avoided.
  • a method according to the invention is characterized by the measures according to claim 1.
  • a vehicle is provided with a motion sickness indicator, which, in an early stage, alerts a driver or a steering system of the vehicle to potentially sickening vehicle motions.
  • the driver or steering system can change the steering of the vehicle in such a way that the sickening motions are avoided or, in any case, do not continue over a longer period of time.
  • a method according to the invention does not involve intervention in the motion-sick person, as known preventatives and methods do, but primarily in the causative source, the vehicle motions. This has a number of advantages.
  • a method according to the invention is more efficient than many of the known preventatives, in that this method can help all occupants of a vehicle at the same time, without having to intervene in each of them separately.
  • This is especially advantageous in large vehicles with many passengers, for example buses.
  • this method causes no adverse side effects in the passengers and is thus suitable for every one, in every situation, as long and as often as needed.
  • the method in contrast to many of the known preventatives, has a wide practical applicability, since the method can be carried out with relatively simple auxiliary means (in particular a motion sickness indicator to be discussed in more detail below). These auxiliary means can simply be fitted in any vehicle or even to one of the passengers, without requiring radical adaptations.
  • the method can simply be 'switched off', for example when none of the occupants is susceptible to motion sickness. In that case, the driver can simply ignore the information provided by the indicator or switch off the motion sickness indicator.
  • a suitable motion sickness indicator for the method can be embodied in various manners.
  • the indicator can comprise, for example, a mass spring system or a body immersed in a liquid that is at rest during permissible vehicle motions and is excited by sickening motions. Then the degree of excitation is a measure for the gravity of the sickening motion.
  • the motion sickness indicator can comprise measuring, evaluation and rendering means, with which the vehicle motion, at any rate at least one of its relevant parameters for motion sickness, is measured and compared with permissible values or motion patterns that are stored in evaluation means. Then, the outcome of this comparison can be presented to the driver with the aid of suitable rendering means.
  • a motion sickness indicator can accurately and timely identify sickening motions and, in addition, provide the driver with further information concerning, for example, the degree of sickening of the motions generated by his steering. In addition, the effect of correcting steering actions can be visualized directly.
  • the acceleration of a motion is a relevant parameter for motion sickness.
  • the acceleration can simply be measured and then compared with a relation between acceleration and motion sickness known from practice. It has been found that on the basis of an acceleration measured in only one direction, a correct prediction can already be made with regard to the sickening effect of a motion. Since motions in general and vehicle motions in particular can usually be provoking with regard to motion sickness in several directions, the accuracy of the prediction can be increased by measuring the acceleration of the vehicle motions three-dimensionally, in other words, in three orthogonal directions. Then the degree of sickening can be predicted for each separate direction. However, preferably one total acceleration signal is calculated on the basis of the three measured acceleration components, after which the prediction is based on this one signal.
  • a second advantage is that this makes the orientation of the measuring means in relation to the vehicle irrelevant. This is favorable in particular when the motion sickness indicator is not integrated in the vehicle, but is to be fitted in the vehicle as a loose instrument.
  • a method according to the invention is characterized by the measures according to claim 6.
  • the relation between the acceleration of a motion and the degree to which this motion can cause motion sickness in an average person can be approximated by a transfer function with a band pass characteristic.
  • the response of an average individual to the vehicle motions can thus simply be predicted by filtering the measured acceleration signal of the motion with such a band pass characteristic.
  • the filtered signal then gives a direct indication of the gravity of the motion sickness.
  • the transfer function can be adjusted to personal conditions with the aid of adjustable weight and amplification factors.
  • the invention relates to an apparatus for detecting and signaling potentially sickening motions, characterized by the measures according to claim 8.
  • the apparatus has been provided with measuring means for measuring a motion parameter that is representative of motion sickness, for example an acceleration of the motion.
  • the measured motion parameter is then, with the aid of evaluation means present in the apparatus, compared with values or patterns known from practice to be permissible from the viewpoint of motion sickness.
  • the evaluation means can also comprise an algorithm in which a relation between the motion parameter involved and its effect on motion sickness is fixed, and on the basis of which the sickening effect of the measured signal can be estimated.
  • the apparatus comprises rendering means, for example a LED, LCD display, alarm or loudspeaker, with which the outcome of the evaluation means can be communicated to the user.
  • rendering means for example a LED, LCD display, alarm or loudspeaker
  • signal processing means can be provided between the measurement and evaluation means, for example for eliminating measurement peaks and measurement noise, in order to obtain a reliable prediction.
  • an apparatus according to the invention is characterized by the measures according to claims 10-12.
  • the degree to which a motion can cause motion sickness can be predicted by the response of a band pass filter to the acceleration of the motions involved.
  • the band pass filter has a peak of around approximately 0.16 Hz, a first cut-off frequency between approximately 0.01 and 0.16 Hz and a second cut-off frequency between approximately 0.16 and 1 Hz.
  • Such a band pass filter can be used to evaluate the sickening effect of the signal measured by the acceleration transducer in a simple yet accurate manner.
  • an apparatus according to the invention is characterized by the measures according to claim 13.
  • the apparatus is preferably provided with adjustment means, in order to tune the sensitivity of the indicator to the susceptibility of a specific interested party, for example a passenger.
  • the adjustment means can comprise, for example, an amplification factor, by which the outcome of the evaluation means is multiplied.
  • the adjustment means can be manually operated means, but can also be of a self-learning nature. In the latter case, adjustment to the individual takes place 'automatically', based on feedback information received from the individual during use.
  • This self-learning embodiment is particularly advantageous when the apparatus is used by only one person or a small number of persons.
  • memory means are provided, in which the personal preferred settings of different users can be stored, so that these can be retrieved with a single preference button.
  • FIG. 1 schematically shows an apparatus 1 according to the invention, hereafter also referred to as motion sickness indicator, for detecting motions that potentially cause motion sickness.
  • the motion sickness indicator 1 comprises measuring means 3, evaluation means 5 connected thereto, and connected to these evaluation means 5 rendering means 7.
  • the measuring means 3 are arranged for measuring a relevant parameter for motion sickness of the motions.
  • the applicant has demonstrated that the acceleration is such a relevant parameter.
  • the measuring means 3 comprise one or more acceleration transducers with which the acceleration of a motion acting on the apparatus 1 during use can be measured, preferably in three orthogonal directions (a x , a y , a z ).
  • the acceleration can be measured in two or only one direction, but since motions can generally be provoking with regard to motion sickness in all three directions, the most accurate prediction can be obtained on the basis of a three-dimensional signal. Acceleration transducers are sufficiently well-known from practice and therefore do not require further specification.
  • the evaluation means 5 are used to predict the sickening effect of the motion on the basis of the measured accelerations.
  • the evaluation means 5 comprise calculation means 8, comparison means 9 and adjustment means 10.
  • the total acceleration signal (a) is then passed through the comparison means 9.
  • These comparison means 9 include knowledge gathered from practice concerning the response of a normal population to such an acceleration signal. This knowledge can be incorporated in the comparison means 9, for example, in the form of a table with permissible threshold values or a permissible acceleration pattern. Preferably, however, this knowledge is fixed in a dynamic model. It has been found that the degree to which an average individual gets motion sick due to a specific motion can be modeled as a band pass characteristic, as shown in Figure 2. This characteristic has both a high-pass and a low-pass character. The high-pass part is used to filter out the gravity acceleration component of the total acceleration signal (a).
  • the high-pass part has a first cut-off frequency (A) of, for example, between approximately 0.01 and 0.16 Hz.
  • the low-pass part has a second cut-off frequency (C) of between approximately 0.16 and 1 Hz.
  • A first cut-off frequency
  • C second cut-off frequency
  • the peak sensitivity (B) of this characteristic is around approxiniately 0.16 Hz.
  • Such a characteristic can be implemented in the evaluation means 5, for example, in the form of a band pass filter.
  • motion sickness can also be predicted on the basis of the separate acceleration components (a x , a y , a z ), whereby the sickening effect can be determined for each acceleration component, optionally with a separate filter.
  • the total acceleration signal has the advantage that, because only the measured acceleration magnitude is used as an input signal for the filter, the orientation of the acceleration transducer in relation to the vehicle becomes irrelevant. This is particularly favorable when the motion sickness indicator can be fitted in the vehicle as a loose instrument.
  • an algorithm can be incorporated that, when evaluating the sickening effect of specific motions, takes the factor time into account, in particular the period during which the sickening motions occur, the motion history of the vehicle from the moment of starting up, and the delay in the response of an average passenger to such sickening motions.
  • a time-dependent algorithm can factor this in.
  • This degree will increase as the sickening motions are more violent and/or continue longer, while the degree will decrease when the sickening motions are temporarily less violent or even completely absent, for example because the driver of the vehicle reacts well to the instantaneous degree and, on the basis of this, corrects his driving behavior, or, for example, because the vehicle is temporarily stationary.
  • the evaluation means 5 can include an algorithm, which can monitor a cumulative measure, which quantifies the sickening effect over the whole drive. This measure is obtained by integrating the instantaneous measure for motion sickness in the time. At a constant vehicle motion, this yields a straight line, as shown in Fig. 3 in interrupted lines, the unit (plotted on the vertical axis, on the right side) being arbitrary. As shown in Fig.3, this measure only increases in time.
  • Such a cumulative drive value has the additional advantage of storing information relating to the driving behavior of the driver. This information can be advantageously employed, for example, for didactic or administrative purposes.
  • the evaluation means 5 comprise adjustment means 10, which can be used to adjust relevant factors for the evaluation, which can vary depending on user or condition of use, such as, for example, the temperature in the vehicle, the age of the occupant or a personal susceptibility factor, with which the susceptibility differences between different users can be factored in.
  • adjustment means 10 can be used to adjust relevant factors for the evaluation, which can vary depending on user or condition of use, such as, for example, the temperature in the vehicle, the age of the occupant or a personal susceptibility factor, with which the susceptibility differences between different users can be factored in.
  • the adjustment means 10 can be equipped in such a manner that the user can adjust them manually, but they can also be of a self-learning nature. In the latter case, the adjustment means will, in the course of use, adopt an optimum value through interaction with the user.
  • memory means (not shown) are provided, in which preferred settings for different users or conditions are stored, so these can be retrieved with a single preference button.
  • the motion sickness indicator 1 is provided with rendering means 7, with which the outcome of the evaluation means 5 can be presented in a suitable manner.
  • rendering means 7 can comprise, for example, a LED or alarm signal to indicate whether the evaluated motions are sickening or not.
  • the indicator 1 can also indicate to what degree the motions are sickening, for example by means of differently colored LEDs (green for non-sickening motions, orange when the motions are on the verge and red when the motions are sickening), a mounting pointer, or an alarm with increasing volume or frequency.
  • the motion sickness indicator can further give instructions on how to adjust the provocative motions in order to minimize the sickening effect. Such information can be shown on an LCD display, for example.
  • An apparatus can be used, for example, in a vehicle to help the driver to control his driving behavior in such a manner that this is as little sickening as possible for a fellow passenger. Since the driver himself does not usually get sick, it is difficult for him to judge to what degree his driving style can cause motion sickness in fellow passengers. Of course these fellow passengers can indicate this themselves, but then it is often too late, in other words, they already feel sick.
  • a motion sickness indicator according to the invention can be used to signal motions associated with motion sickness at an early stage, long before these actually cause motion sickness, and allows the driver to adjust his driving style in time.
  • the motion sickness indicator 1 can be fitted in the vehicle or to a passenger prior to the drive.
  • the indicator can also be integrated in the vehicle as a standard accessory.
  • the term 'vehicle' is to be construed in a broad sense, including at least any means of transport on land, but vessels and aircraft also belong to the means of transport for which application of the motion sickness indicator 1 is possible.
  • the thus installed motion sickness indicator 1 will evaluate the motions present in the car during the drive for their sickening effect and will give feedback on the outcome to the driver or a steering system of the vehicle.
  • the information presented is differentiated on the basis of the origin of the motions (braking, accelerating, bends), so the driver can see exactly which driving actions cause motion sickness and how he can adjust these.
  • angular speed can be used to predict motion sickness.
